FOR DENTAL USE ONLY
Introduction
Congratulations on the purchase of Detect™.
1. Indications for Use
The Detect™is an electronic device used for apex location determination and working length
determination. This product must only be used in hospital environments, clinics or dental
offices by qualified dental personnel.
2. Contraindications
The Detect™is not recommended for use in patients that have a pacemaker or other
implanted electrical devices.
3. Warnings (See Contraindications)
See above.
• Onlyusetheoriginalcharger.
4. Precautions
The Detect™device must be used with the manufacturer’s original accessories only.
In order to prevent infectious agent transmission it is highly recommended to use a rubber
dam system during the endodontic procedure.
To ensure that short circuits do not impair the measurements, be particularly careful with
patients fitted with metal crowns or bridges (avoid any metallic contact with the file or the
lip clip).
• Highconcentrationsofsodiumhypochloritemayresultinaloweraccuracy.Forworking
length determination, we recommend to use sodium hypochlorite solution at maximum
3% concentration.
• Makesurethatthecanaliswetenoughtoensurereliabilityofthemeasurement.
• Ensurethattheledoesnottouchanotherinstrument.
• DonotexposeDetect™toanyliquid.
• Avoidexcessiveliquidsinsidethetoothcavitytopreventoverowand
incorrect measurements.
• Detect™must be stored in normal temperature (<60°C) and humidity conditions.
• Donotuseinthepresenceofammableproducts.
• Teethwithopenapiceswillgiveimpreciseresults.
• Ifthebargraphsuddenlymakesalargemovementintheupperpartofthecanal–
continue slightly towards the apex so the signal returns normal.
• Anapexlocatormaynotbeabletomeasureinallconditions.Inanycase,itis
recommended to take an X-Ray prior to use of the unit and compare the information
given by both means.
• For your own safety, please wear personal protective equipment (gloves, glasses, mask).

B. Recharging the Battery
The Detect™is delivered with a rechargeable battery.
On the Detect™a screen indicator shows the level of the battery charge. When this is
ashing,thebatteryrequiresrecharging.However,itisstillfunctionalforseveraltreatments
before the battery shuts down.
Procedure for recharging the battery:
1.Disconnect the measurement cable
2.Connect the charger cable to the Detect™
3.Connect the charger to the mains
Charging screen will appear during battery charging. When the battery image on the
screen stops blinking and turns green, the charging is complete.
CHARGING SCREEN COLOR GUIDE
Duration of charging: About 12 hours (24 hours after long periods without use).
Note: Detect™cannot be used while charging.

D. Getting Started
1.Disconnect the charger from the device if connected.
2.ConnectthemeasurementcableandswitchthedeviceOn–afterashortlogo
presentation, the main screen is displayed and the cursor on the tooth image will start
blinking.
 (WhileturningthedeviceOnwithoutthemeasurementcable–themainscreenwillbe
displayed without cursor on the tooth image).
3.Attach the lip clip to the patient.
4.Inserttheleintothecanal–(toensureprecisemeasurementsthelesizeshouldbe
adjusted to the canal diameter).
5.Connect the hook to the file.
The cursor on the tooth will stop blinking (accompanied by a double beep signal).
A blinking cursor and no sound signal indicate a faulty connection. Check your connections,
clean your hook connection, moisten the canal, if necessary, and start again.
No other adjustments are necessary before starting measurement.
Note: Connection test feature is included in Detect™ in order to check the cables:●
• Connectmetalpartoftheconnectionhooktothelipclip
• “Connectiontest”iconshouldappearinthebottomleftcornerofthedisplay,
indicating proper connection
• Ifnoiconappears,theconnectionhookorthemeasurementcableshouldbereplaced
E. Searching for the Apex
1. Coronal and Medial Zone
Slowly introduce the file into the canal. The cursor on the tooth icon indicates the progression
of the file inside the canal.
Further progression of the file in the canal is shown both by the cursor on the tooth icon
and by the numerical value on the graphical scale (which does not represent length in
millimeters). Detect™emits audible information of file progression via a series of progressive
rate beeps.

10
11
F. Sound Adjustment
Detect™is equipped with a sonic indicator which enables monitoring of the progression of
the file within the canal.
Thisfunction,inconjunctionwiththedisplayofprogression,enablesworking“blind”while
still monitoring the progression of the file.
The volume can be adjusted to one of four levels: mute, low, normal and high, by successive
presses on the volume key.
G. Demo Mode
The built-in Demo mode is available to become acquainted with the device and to
demonstrate its operation.
1.Disconnect the measuring cable or the charger from the device if connected and turn
Off the device.
2.To start Demo mode, press and hold the (On/Off) button for about 2 sec. until the
secondbeepsoundsand“Demo”indicationappearsinthebottomleftcornerofthe
display.
3.During Demo cycle device operating sequence is shown on the screen. Press button
to pause the simulation; press button again to resume.
4.When Demo cycle is completed, it is repeated automatically until interrupted by
the operator.
5.To exit Demo mode press button and hold
it for about 2 sec. until a beep sounds.
Note: If measurement cable is connected to
Detect™ during Demo cycle, the device switches
automatically to normal operation mode
H. Automatic Shutdown
Detect™automatically shuts down after 5 minutes without use. It is advisable, however, to
manually switch off equipment after measurement by simply pressing the key (On/Off).
BEGINNING OF APICAL ZONE MIDDLE OF APICAL ZONE APICAL POSITION
2) Apical Zone
Theapicalzoneisdividedinto10segmentsgraduatedfrom0.9to0.0(apex)asvisual
information of file progression.
Whentheapexisreached,thecursorshows“APEX”andasolidtoneisemitted.
Once apex is reached, it is recommended to subtract 0.5 mm to determine the working
length for shaping.
3) Over-Instrumentation
A red segment and a warning signal indicate that the file has passed the apex. The cursor
onthetoothiconshows“OVER”.
